lat, lon, h (latitude, longitude, height) are the coordinates of the point where you want to calculate the incidence angle
Img is the image relative to the incidence angle you want to calculate
DirSite is the directory of your project
if you use sarproz in matlab, use the interface to load your project
then type “fast” and hit enter

what is that you do not understand, please be specific.

Yours looks like a GCP problem. Chekc the documentation and the tutorials for that.
Now, what you can do is using this function https://sarproz.com/manual/geo_shifts_gui.html to correct it back

You must use the run time compiler corresponding to the version that was used at compilation time
you have no choice
it’s written in the readme.txt file you got with the executable file

The fact that the operation cannot be performed and no errors are reported,
it does not reveal any bugs,
it simply means that the default parameters you are using are not appropriate for your case.
Firstly, you should check the forum.
A quick search would you lead you e.g. the the following…[Read more]

Hi Aleksandra,
if you get an error, send us the lasterror.mat file and the log file. Periodically we have troubles with forum files attachments, but if you make a .zip file containing mat and log files, you should be able to attach it.
Concerning the bridge monitoring, it’s a non-standard analysis which requires some work. Usually we don’t provide…[Read more]

Hi Fatchur,
yours is not the last update. Please update the sw using the manage version module and try again. Should you get again an error, zip lasterror and log files before uploading them

Your comment does not match this discussion, which is around an urban area.
The distribution of the residual height should be at zero, which means, the reference point is close to the external DEM you used, and if you are in an urban area (and the DEM is in fact a DTM), this implies it’s on the ground (not on buildings).
But you are on the…[Read more]

From Minos:
“Hello Marisa,
I had the same problem once.
What you have to do is the following
Go to: C:UsersAppDataLocalTempmcrCache8.3main_… and delete the folder.

Keep in mind that you have to be able to see “hidden…[Read more]

Thank you,
we have fixed it

The _mask file tells you where the phase was unwrapped and where it was not
the image with no scale is a bug. we are going to upload soon a fix
best

I do not know what you mean with “phase ambiguity parameter”.
The phase ambiguity is pi=3.1416… radians
If you convert the phase to height or displacement, you will get the corresponding values. Check any insar paper for the formulas.

Since a few months we developed a new module called “View/Export Extended Data/Results”.
Here the full description: https://sarproz.com/manual/plot_par_mod.html
Please update your software version if you have an old one.
We are still improving it, so, you could find minor bugs/changes.
The idea is that you can do what you want, using…[Read more]

Not sure why you get date_1, can you paste an example here?
You should get the explanation in the first line of the csv file. Something like: “28 data entries plus 28 estimated movement entries ” and ” from 20081025 to 20091217 “.
This says that in the first series of dates you get the actual data, in the second series you get the model chosen to…[Read more]

The “Filter/Matrix visualization” function in “Scatter Plots” displays scattered data in matrix a form. In Matlab this is much faster rather than displaying scattered points directly. It basically consists in re-sampling your scattered data on a regular grid. This operation corresponds to a spatial filter. And you can actually apply a filter…[Read more]

Hi Asterios,
the general answer is: you would need to take a Sarproz course, where we teach exactly this, that is, how to judge and improve your results without any prior knowledge.
More in detail, always start with the easiest and default approach: linear trend, automatic and default choices. The software extracts and suggest you numbers,…[Read more]

CSV file fields:

ID – point reference id (sequential)
LAT, LON – latitude and longitude
SVET, LVET – sample and line, pixel SAR coordinates
HEIGHT – relative to sea level (m)
HEIGHT WRT DEM – relative to the external DEM (m)
SIGMA HEIGHT – height estimation standard deviation
VEL – deformation velocity in mm/year
SIGMA VEL – velocity standard de…[Read more]
